Re: Had Poison Ivy, Now Have Hives!!!

When I was researching for my book "The Poison Oak & Poison Ivy Survival Guide, I never saw mention of hives along with poison oak or poison ivy.

Poison Oak is a delayed type hypersensitivity (allergy—with hours to days for a reaction), and hives are an immediate type hypersensitivity (allergy—with no more than 30 minutes for a reaction).

So, hives would not be part of a poison ivy/oak allergic reaction. I would suspect cortisone. The internet lists cortisone products (including pregnisone) as causing hives as one of many possible side effects.
